我国における飲料製品は、生活スタイルの変化や飲食に対する嗜好の多様化に応えるため、その種類は年々増加し続けている。特に、所定の容器中に封入され、そのままの状態で飲用可能な所謂RTD(Ready to Drink)形態の容器詰飲料が飲料製品全体でも主流となっている。更に、RTD形態の容器詰飲料は、紙製容器等が用いられ冷蔵保管が必要な所謂チルド製品と、缶やペットボトルといった常温で長期間の保存が可能な所謂ドライ製品とに分類されるが、圧倒的にドライ製品が大きな市場規模を有している。 The types of beverage products in Japan continue to increase year by year in order to respond to changes in lifestyle and diversification of tastes for eating and drinking. In particular, so-called RTD (Ready to Drink) -type packaged beverages, which are sealed in a predetermined container and can be drunk as they are, have become the mainstream in all beverage products. Further, RTD-type packaged beverages are classified into so-called chilled products that require refrigerated storage using paper containers and the like, and so-called dry products that can be stored for a long period of time at room temperature such as cans and PET bottles. Overwhelmingly, dry products have a large market size.
昨今の食と健康に対する意識の高まりもあって、身体に対する生理活性機能を備えた、所謂機能性飲食品に注目が集まっている。飲料製品もこの例外ではなく、既にトクホ飲料と称される製品が多種上市されており、これに加えて、昨今では、健康増進法等に定められた上記の特定保健用食品(トクホ)や、栄養機能食品の対象とは別に、一定の要件を備えることで食品への機能性表示が認められるという、新たな機能性飲料の制度にも期待が寄せられている。 Due to the recent increase in awareness of food and health, so-called functional foods and drinks having a bioactive function for the body are attracting attention. Beverage products are no exception to this, and various products called Tokuho beverages have already been put on the market. In addition to this, recently, the above-mentioned foods for specified health use (Tokuho) stipulated in the Health Promotion Law, etc. Apart from the target of nutritionally functional foods, there are also expectations for a new functional beverage system in which functional labeling is permitted on foods by satisfying certain requirements.
生理活性機能を発揮する可能性がある成分の一つとして、近年注目されている物質の一つに水素がある。水素を高濃度で水に溶解させた、所謂「水素水」は、溶存水素の身体に対する具体的な挙動や、作用メカニズムの詳細については依然不明であるものの、分子状の水素が体内の活性酸素(酸素ラジカル)を除去する効果があるとされ、これによってさまざまな健康増進作用を促進するものとして期待されている。水素水は、缶やパウチ形態等の容器に封入された水素水製品として流通している。 Hydrogen is one of the substances that has been attracting attention in recent years as one of the components that may exert a physiologically active function. In so-called "hydrogen water" in which hydrogen is dissolved in water at a high concentration, the specific behavior of dissolved hydrogen on the body and the details of the mechanism of action are still unknown, but molecular hydrogen is the active oxygen in the body. It is said to have the effect of removing (oxygen radicals), and is expected to promote various health-promoting effects. Hydrogen water is distributed as hydrogen water products enclosed in containers such as cans and pouches.
水素水のように、水素自体の生理活性機能に着目した飲料に関しては、例えば、茶類、果実・野菜類等からなる機能性原料を水素水に配合した水素含有飲料に係る発明が提案されている(特許文献1参照)。また、水素を水に溶解させる方法として、ガス透過膜を介して原料水に所定圧に加圧した水素を溶解させる工程と、溶解後の水素水の水素濃度を測定する工程と、水素濃度が所定範囲になるように、加圧水素の圧力を調整する工程を備えた飲料用水素含有水の製造方法が提案されている(特許文献2参照)。 Regarding beverages that focus on the physiologically active function of hydrogen itself, such as hydrogen water, for example, an invention relating to a hydrogen-containing beverage in which a functional raw material consisting of teas, fruits, vegetables, etc. is mixed with hydrogen water has been proposed. (See Patent Document 1). Further, as a method of dissolving hydrogen in water, there are a step of dissolving hydrogen pressurized to a predetermined pressure in raw material water through a gas permeable membrane, a step of measuring the hydrogen concentration of the dissolved hydrogen water, and a step of measuring the hydrogen concentration. A method for producing hydrogen-containing water for drinking, which includes a step of adjusting the pressure of pressurized hydrogen so as to fall within a predetermined range, has been proposed (see Patent Document 2).
水素水において水中に含まれる水素の含有量は最も重要な要素であり、水素が有効成分として作用することを鑑みれば、その含有量は高いほうが望ましい。しかしながら、水素は水に対して難溶解性であって、その飽和溶解量は、20℃で0.16mg/100mL(約1.6mg/L(1.6ppm))、0℃で0.19mg(1.9mg/L(1.9ppm))と微量であり、且つ非常に軽い気体であることから、一旦溶解した水素が短時間で外部に抜け出てしまいやすい。水素の抜け出しを完全に防ぐことは非常に困難であることから、水素濃度の低下を可能な限り抑制する方法が強く求められている。
このような観点のもと、水溶液等をゲル化させて水素ガスの微細気泡を保持する機能性ゼリーの製造方法が提案されている(特許文献3参照)。
The content of hydrogen contained in water in hydrogen water is the most important factor, and considering that hydrogen acts as an active ingredient, it is desirable that the content is high. However, hydrogen is sparingly soluble in water, and its saturated dissolution amount is 0.16 mg / 100 mL (about 1.6 mg / L (1.6 ppm)) at 20 ° C. and 0.19 mg (0.19 mg / L (1.6 ppm)) at 0 ° C. Since it is a very light gas with a very small amount of 1.9 mg / L (1.9 ppm)), hydrogen once dissolved tends to escape to the outside in a short time. Since it is extremely difficult to completely prevent the escape of hydrogen, there is a strong demand for a method of suppressing the decrease in hydrogen concentration as much as possible.
From this point of view, a method for producing a functional jelly in which an aqueous solution or the like is gelled to retain fine bubbles of hydrogen gas has been proposed (see Patent Document 3).
特許文献3には、水素ガスの保持性に関する検証結果が開示されていない。また、特許文献3の方法は、高粘度または高硬度のゼリー状となるまでゲル化させることで水素ガスを保持しようとする発明であると認められ、例えば低粘度等した場合でも水素ガスを十分に保持できるか否かは不明であった。 Patent Document 3 does not disclose the verification result regarding the retention of hydrogen gas. Further, the method of Patent Document 3 is recognized as an invention in which hydrogen gas is retained by gelling until it becomes a jelly with high viscosity or high hardness. For example, hydrogen gas is sufficiently retained even when the viscosity is low. It was unclear whether it could be retained in.
本発明は、水素ガスを含有する組成物において水素ガスの保持性を高めることのできる水素ガス保持剤を提供することを目的とする。また、本発明は、水素ガスの保持性の高い水素ガス含有組成物、その製造方法および水素ガス保持方法を提供することをさらなる目的とする。 An object of the present invention is to provide a hydrogen gas retainer capable of enhancing the retention of hydrogen gas in a composition containing hydrogen gas. Another object of the present invention is to provide a hydrogen gas-containing composition having high hydrogen gas retention, a method for producing the same, and a method for retaining hydrogen gas.

以下、本発明の実施形態について説明する。
〔水素ガス保持剤〕
(寒天(1))
本発明の一実施形態に係る水素ガス保持剤は、水素ガス含有組成物に用いられるものであり、日寒水式で測定されるゼリー強度(単位:g/cm2)から得られる無次元数(A)と、重量平均分子量から得られる無次元数(B)とが、下記条件1を満たす寒天(1)を有効成分とする。
(条件1) B ≦ 625A + 25×104
Hereinafter, embodiments of the present invention will be described.
[Hydrogen gas retainer]
(Agar (1))
Hydrogen retention agent according to one embodiment of the present invention are those used in the hydrogen gas-containing compositions, jelly strength measured in days Hiyamizu formula (Unit: g / cm 2) a dimensionless number obtained from The active ingredient is agar (1) in which (A) and the dimensionless number (B) obtained from the weight average molecular weight satisfy the following condition 1.
(Condition 1) B ≤ 625A + 25 × 10 4
寒天は、テングサ属、オゴノリ属、オバクサ属などの海藻原料より抽出され、広く利用されているゲル化剤の一つである。 Agar is one of the widely used gelling agents extracted from seaweed raw materials such as Gelidiaceae, Gracilaria, and Obakusa.
寒天分子は、溶液でのランダムコイル状態から、二重螺旋状に会合し、かかる二重螺旋状構造がさらに会合して三次元網目構造を形成することが知られている。上記条件1を満たす寒天(1)は、三次元網目構造が十分に形成されていないと考えられる低粘度(例えば、20mPa・s以下)の状態であっても水素を保持し得ることから、二重螺旋状の構造が水素分子の保持に寄与している可能性が考えられる。後述する実施例にて示すように、ゼリー強度が同程度あるいは若干小さい寒天であっても、重量平均分子量が小さいものは水素保持性が高い傾向が認められるところ、分子間で上記二重螺旋状構造を形成しやすいことがその一因である可能性が考えられる。
ただし、本実施形態はかかる作用機序に限定されるものではない。
It is known that agar molecules associate in a double helix form from a random coil state in a solution, and such double helix structures further associate to form a three-dimensional network structure. The agar (1) satisfying the above condition 1 can retain hydrogen even in a low viscosity state (for example, 20 mPa · s or less), which is considered that the three-dimensional network structure is not sufficiently formed. It is possible that the double helix structure contributes to the retention of hydrogen molecules. As shown in Examples described later, even if the agar has the same or slightly lower jelly strength, the one having a small weight average molecular weight tends to have high hydrogen retention. It is possible that one of the reasons is that it is easy to form a structure.
However, this embodiment is not limited to such a mechanism of action.
(ゼリー強度)
ここで、日寒水式で測定されるゼリー強度(単位:g/cm2)とは、寒天の性質を表す指標の一つであり、寒天の1.5%溶液を調製し、20℃で15時間放置、凝固せしめたゲルについて、その表面1cm2当たり20秒間耐え得る最大重量(g)として定義される。寒天(1)のゼリー強度の範囲は、ゼリー強度から得られる無次元数(A)が上記条件1を満たすものであれば特に制限されないが、下限値は、例えば1g/cm2以上とすることができ、さらには5g/cm2以上とすることができる。また、ゼリー強度から得られる無次元数(A)が上記条件1を満たす限りゼリー強度の上限値も特に制限されないが、例えば2500g/cm2以下とすることができ、さらには2000g/cm2以下とすることができる。
(Jelly strength)
Here, jelly strength measured in days Hiyamizu formula (Unit: g / cm 2) and is an index representing the nature of the agar, 1.5% solution of agar was prepared at 20 ° C. For a gel that has been left to stand for 15 hours and solidified, it is defined as the maximum weight (g) that can withstand 20 seconds per 1 cm 2 of its surface. The range of the jelly intensity of the agar (1) is not particularly limited as long as the dimensionless number (A) obtained from the jelly intensity satisfies the above condition 1, but the lower limit value is, for example, 1 g / cm 2 or more. Further, it can be 5 g / cm 2 or more. Further, as long as the dimensionless number (A) obtained from the jelly strength satisfies the above condition 1, the upper limit of the jelly strength is not particularly limited, but can be, for example, 2500 g / cm 2 or less, and further 2000 g / cm 2 or less. Can be.
(重量平均分子量)
また、寒天(1)の重量平均分子量も、重量平均分子量から得られる無次元数(B)が上記条件1を満たす限り特に制限されないが、例えば、下限値は1×104(1万)以上とすることができ、さらには3×104(3万)以上とすることができる。また、上限値は200×104(200万)以下とすることができ、さらには160×104(160万)以下とすることができる。なお、寒天の重量平均分子量は、ゲルろ過クロマトグラフィーにより測定することができる。
(Weight average molecular weight)
The weight average molecular weight of agar (1) is not particularly limited as long as the dimensionless number obtained from the weight-average molecular weight (B) satisfies the above condition 1, for example, the lower limit is 1 × 10 4 (1 50,000) or Further, it can be 3 × 10 4 (30,000) or more. The upper limit may be a 200 × 10 4 (200 50,000) or less, further may be a 160 × 10 4 (160 50,000) or less. The weight average molecular weight of agar can be measured by gel filtration chromatography.
上記寒天(1)は、水素保持性の観点から、さらに下記条件1’を満たすことが好ましい。
(条件1’) B ≧ 400A
上記条件1’を満たす寒天は、寒天分子が、ゼリー強度との関係において所定以上の重量平均分子量(すなわち十分な大きさ)を有しているものといえ、この点が水素保持性にさらに寄与している可能性が考えられる。
From the viewpoint of hydrogen retention, the agar (1) preferably further satisfies the following condition 1'.
(Condition 1') B ≧ 400A
It can be said that the agar molecule satisfying the above condition 1'has a weight average molecular weight ( that is, a sufficient size) equal to or higher than a predetermined value in relation to the jelly strength, and this point further contributes to hydrogen retention. It is possible that you are doing this.
(寒天(2),(3))
本発明の他の一実施形態に係る水素ガス保持剤は、下記条件2を満たす寒天(2)、および/または下記条件3を満たす寒天(3)を有効成分とするものである。
(条件2) ゼリー強度が1〜250g/cm2、かつ、重量平均分子量が1×104〜20×104
(条件3) ゼリー強度が1500〜2500g/cm2、かつ、重量平均分子量が60×104〜160×104
寒天(2)および寒天(3)は、それぞれ1種類ずつを用いてもよく、これら2種類を併用してもよい。
(Agar (2), (3))
The hydrogen gas retainer according to another embodiment of the present invention contains agar (2) satisfying the following condition 2 and / or agar (3) satisfying the following condition 3 as an active ingredient.
(Condition 2) Jelly strength is 1 to 250 g / cm 2 , and weight average molecular weight is 1 × 10 4 to 20 × 10 4.
(Condition 3) The jelly strength is 1500 to 2500 g / cm 2 , and the weight average molecular weight is 60 × 10 4 to 160 × 10 4.
One type of agar (2) and one type of agar (3) may be used, or these two types may be used in combination.
(寒天(2))
上記寒天(2)において、ゼリー強度は1〜250g/cm2であり、5〜100g/cm2であることがより好ましく、10〜50g/cm2であることがさらに好ましい。また、上記寒天(2)の重量平均分子量は1×104〜20×104であり、2×104〜15×104であることがより好ましく、4×104〜10×104であることがさらに好ましい。
ゼリー強度および重要平均分子量が上記範囲にある寒天(2)は、水素ガス含有組成物が低粘度であっても水素ガス保持性に特に優れたものとなる。ここで、寒天(2)は、ゼリー強度および重量平均分子量が小さな値をとる寒天ということができる。かかる寒天(2)が水素ガス保持性に優れる理由は必ずしも明らかではないが、寒天(2)は三次元網目構造を形成しにくい一方で、分子間で上記二重螺旋状構造を形成しやすいと考えられ、このことが効率的な水素ガス保持性に寄与している可能性が考えられる。
(Agar (2))
In the agar (2), the jelly strength was 1~250g / cm 2, more preferably from 5 to 100 g / cm 2, further preferably 10 to 50 g / cm 2. The weight average molecular weight of the agar (2) is 1 × 10 4 to 20 × 10 4 , more preferably 2 × 10 4 to 15 × 10 4 , and 4 × 10 4 to 10 × 10 4 . It is more preferable to have.
Agar jelly strength Contact and important average molecular weight is in the above range (2) is a hydrogen gas-containing composition is particularly excellent in hydrogen gas retention even at a low viscosity. Here, agar (2) can be jelly strength Contact and weight average molecular weight of agar to take a small value. The reason why such agar (2) is excellent in hydrogen gas retention is not necessarily clear, but it is said that while agar (2) is difficult to form a three-dimensional network structure, it is easy to form the double helix structure between molecules. It is conceivable that this may contribute to efficient hydrogen gas retention.
(寒天(3))
一方、上記寒天(3)において、ゼリー強度は1500〜2500g/cm2であり、1600〜2200g/cm2であることがより好ましく、1700〜2000g/cm2であることがさらに好ましい。また、上記寒天(3)の重量平均分子量は60×104〜160×104であり、80×104〜150×104であることがより好ましく、90×104〜140×104であることがさらに好ましい。
ゼリー強度および重要平均分子量が上記範囲にある寒天(3)は、水素ガス含有組成物が低粘度であっても水素ガス保持性に特に優れたものとなる。ここで、寒天(3)は、ゼリー強度および重量平均分子量が大きな値をとる寒天ということができる。かかる寒天(3)が水素ガス保持性に優れる理由は必ずしも明らかではないが、寒天(3)は分子同士のみならず分子内でも二重螺旋状構造を形成することができるものと考えられ、このことが効率的な水素ガス保持性に寄与している可能性が考えられる。
(Agar (3))
On the other hand, in agar (3), jelly strength is 1500~2500g / cm 2, more preferably 1600~2200g / cm 2, further preferably 1700~2000g / cm 2. The weight average molecular weight of the agar (3) is 60 × 10 4 ~160 × 10 4 , more preferably from 80 × 10 4 ~150 × 10 4 , at 90 × 10 4 ~140 × 10 4 It is more preferable to have.
Agar jelly strength Contact and important average molecular weight is in the above range (3), a hydrogen gas-containing composition is particularly excellent in hydrogen gas retention even at a low viscosity. Here, agar (3) can be jelly strength Contact and weight average molecular weight of agar to take a large value. The reason why such agar (3) is excellent in hydrogen gas retention is not necessarily clear, but it is considered that the agar (3) can form a double helix structure not only between molecules but also within the molecules. It is possible that this contributes to efficient hydrogen gas retention.

[Test Example 3]
The agar shown below (both manufactured by Ina Food Industry Co., Ltd.) was dissolved in hot water with ion-exchanged water to prepare a 4-fold concentrated solution. A packaged hydrogen gas-containing composition was produced in the same manner as in Test Example 1 except that such a concentrated solution was used, the viscosity was measured, and the hydrogen concentration was measured over time.
Agar 1: Product name "Ultra Agar Ena", jelly strength 30 g / cm 2 , weight average molecular weight 6 x 10 4
Agar 2: Product name "Ina Agar Soft", jelly strength 200 g / cm 2 , weight average molecular weight 45 x 10 4
Agar 3: Product name "elastic agar Yamato", jelly strength 600 g / cm 2 , weight average molecular weight 78 x 10 4
Agar 4: Product name "Ina Agar S-6", jelly strength 640 g / cm 2 , weight average molecular weight 45 x 10 4
Agar 5: Product name "Ina agar crispy can", jelly strength 1800 g / cm 2 , weight average molecular weight 92 x 10 4
The results are shown in Table 3.
なお、上記寒天のゼリー強度は、日寒水式に従い、(寒天濃度1.5質量%,溶解条件110℃,10分)に従って測定した。
また、重量平均分子量は、HPLCによるGPC法に従って測定した。具体的には、寒天0.3gを200mLの蒸留水に溶解(110℃,5分)し、カラム(TOSOH TSK-GEL for HPLC,TSK-GEL GMPWXL)を使用して測定した。
The jelly intensity of the agar was measured according to the daily agar formula (agar concentration 1.5% by mass, dissolution condition 110 ° C., 10 minutes).
The weight average molecular weight was measured according to the GPC method by HPLC. Specifically, 0.3 g of agar was dissolved in 200 mL of distilled water (110 ° C., 5 minutes) and measured using a column (TOSOH TSK-GEL for HPLC, TSK-GEL GMPWXL).
表3に示すように、本発明の要件を満たす寒天1、4および5は、水素保持性に優れるものであった。
なお、試料10(寒天1)および試料14(寒天5)は、低粘度(すなわち5mPa・s程度)であっても優れた水素保持性が発揮されている点において、高粘度である試料13(寒天4)よりも好ましいものということができる。
一方、試料11で用いた寒天2は、試料10の寒天1よりも重量平均分子量が大きく、また試料12で用いた寒天3は試料10の寒天1よりも重量平均分子量およびゲル強度が大きいものであるが、十分な水素保持性を有していなかった。
As shown in Table 3, the agars 1, 4 and 5 satisfying the requirements of the present invention were excellent in hydrogen retention.
Sample 10 (agar 1) and sample 14 (agar 5) have high viscosities in that excellent hydrogen retention is exhibited even at low viscosity (that is, about 5 mPa · s). It can be said that it is preferable to agar 4).
On the other hand, the agar 2 used in the sample 11 has a larger weight average molecular weight than the agar 1 in the sample 10, and the agar 3 used in the sample 12 has a larger weight average molecular weight and gel strength than the agar 1 in the sample 10. However, it did not have sufficient hydrogen retention.
本発明によれば、所定の寒天を含有させるという簡易な方法により、水素ガス含有組成物において水素ガスの保持性を高めることができるため、多様な飲食品に対し好適に適用することができる。 According to the present invention, since the retention of hydrogen gas can be enhanced in the hydrogen gas-containing composition by a simple method of containing a predetermined agar, it can be suitably applied to various foods and drinks.
